ABSTRACT

Objective:To explore the differences of renal dynamic imaging parameters between operation group and non-operation group in infants with severe hydronephrosis, so as to accumulate theoretical basis for diuretic renal scintigraphy to help the treatment decision making.Methods:A total of 107 infants (age: 3(2, 6) months; 90 males and 17 females) with severe hydronephrosis, who underwent diuretic renal scintigraphy between March 2018 and October 2021 in Shanxi Children′s Hospital were retrospectively reviewed. All patients were diagnosed with ureteropelvic junction obstruction and divided into operation group ( n=87) and no-operation group ( n=20). The differences of differential renal function (DRF), peak time, half-time and drainage curve between the two groups were compared with the independent-sample t test or χ2 test, and the correlation between the renal function of the affected side and the anteroposterior pelvic diameter (APD) was analyzed with Pearson correlation analysis. Results:The operation group included 17 patients with DRF<40%, 60 patients with DRF between 40%-55%, and 10 patients with DRF>55%(supernormal renal function). The 40%-55% was considered as normal DBF, and the rest were abnormal. Infants with abnormal renal function in the operation group ( n=27) were more than those in the non-operation group ( n=3), but there was no statistical difference ( χ2=2.07, P=0.150). The proportion of obstruction curve in the operation group (85.1%, 74/87) was significantly higher than that in the non-operation group (55.0%, 11/20; χ2=7.24, P=0.007). Compared with the non-operation group, the peak time of affected kidney in the operation group was significantly longer ((22.77±7.52) vs (15.26±10.29) min; t=3.78, P<0.001), as well as the peak time of contralateral kidney ((11.25±8.47) vs (6.65±5.75) min; t=2.30, P=0.023). There was a negative correlation between the DRF of the affected side and the APD ( r=-0.48, P<0.001). Conclusions:The DBF is mostly in the normal range in infants with severe hydronephrosis, and supernormal renal function is common. The previous operation indication (DRF<40%) is not suitable for the infants, and it needs to be analyzed combined with the type of curve and the APD determined by color Doppler ultrasound. The prolongation of contralateral renal peak time may be an important parameter for the surgical evaluation of severe hydronephrosis in infants.

ABSTRACT

BACKGROUND@#LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer.@*METHODS@#We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels.@*RESULTS@#On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]).@*CONCLUSION@#LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile.@*TRIAL REGISTRATION@#ClinicalTrials.gov, NCT04563936.

ABSTRACT

Objective:To assess the safety and feasibility of complete lateral position endoscopic combined intra-renal surgery (ECIRS) in treatment of staghorn kidney calculi.Methods:The clinical data of 105 patients with staghorn kidney calculi from March 2016 to July 2022 in the First Hospital of Shanxi Medical University were retrospectively analyzed. Among them, 55 patients were treated with lateral position percutaneous nephrolithotomy (PCNL) (PCNL group), and 50 patients were treated with complete lateral position ECIRS (ECIRS group). The operative time, removal time of double J-tube, postoperative hospital stay, postoperative hemoglobin decrease value, operative complications (using Clavien-Dindo grading criteria), additional postoperative intervention and calculi free rate were compared between two groups.Results:Both groups of patients were successfully operated. The operative time, postoperative hemoglobin decrease value and rate of additional postoperative intervention in ECIRS group were significantly lower than those in PCNL group: (98.3 ± 19.1) min vs. (103.4 ± 16.5) min, (9.34 ± 3.04) g/L vs. (12.55 ± 4.75) g/L and 8.00% (4/50) vs. 21.82% (12/55), the calculi free rate was significantly higher than that in PCNL group: 90.00% (45/50) vs. 74.55% (41/55), and there were no statistical differences ( P<0.05 or <0.01); there were no statistical differences in the removal time of double J-tube, postoperative hospital stay, incidence of Clavien-Dindo≥ grade Ⅱ operative complications between two groups ( P>0.05). Conclusion:The complete lateral position ECIRS is a safe and effective treatment for staghorn kidney calculi, and is a good complement to the ECIRS technique because of its high stone free rate in phase Ⅰ, low complication incidence and easy dissemination.

ABSTRACT

Background Tinnitus is a common symptom in workers exposed to noise, and no specific treatment is available yet. Paying attention to the influencing factors of tinnitus is very important to prevent tinnitus. Objective To investigate the situation of tinnitus among noise-exposed workers and its influencing factors. Methods Using a cross-sectional study design, 1011 noise-exposed male workers in Hangzhou were studied. Tinnitus status, age, education, personal protection, smoking history, drinking history, and family history of the participants were surveyed by questionnaires. Binaural pure tone hearing threshold test was performed on all study subjects. The environmental noise in the workplace was measured. The relationships of tinnitus with noise exposure intensity, noise exposure time, noise exposure category, cumulative noise exposure, and wearing hearing protectors among the noise-exposed workers were analyzed by logistic regression. Results The prevalence of tinnitus among the noise-exposed workers was 36.1%. The mean hearing thresholds at 500, 3000, 4000, and 6000 Hz in the right and left ears were higher in the tinnitus group than in the non-tinnitus group (P<0.05); the hearing threshold at 2000 Hz in the right ear was higher in the tinnitus group than in the non-tinnitus group (P<0.05). There was no statistically significant difference between the two groups in the prevalence of monaural speech-frequency hearing loss or monaural high-frequency hearing loss (P>0.05). The on-site noise intensity was divided into three groups: <85, 85-<95, and ≥95 dB(A); the prevalence of tinnitus in the three groups was 19.6%, 40.5%, and 66.7% respectively. The years of noise exposure was divided into three groups: <1, 1-<5, and ≥5 years; the prevalence of tinnitus in the three groups was 17.9%, 34.0%, and 45.4% respectively. The cumulative noise exposure was divided into six groups: <80, 80-<85, 85-<90, 90-<95, 95-<100, and ≥100 dB(A)·year; the prevalence of tinnitus in the six groups was 6.8%, 25.0%, 31.0%, 39.6%, 43.1%, and 46.7% respectively. The prevalence of tinnitus was higher in the non-stationary noise group (42.5%) than in the stationary noise group (26.8%) (χ2=26.18, P<0.01), and the prevalence in the group without or with hearing protection was 39.7% and 35.5% respectively. The results of logistic regression showed that workers exposed to higher intensity, longer noise exposure, higher cumulative noise exposure, and non-stationary noise (reference: stationary noise) resulted in a higher risk of tinnitus (Ptrend<0.01 or P<0.01); workers wearing of hearing protection device versus those not showed a lower risk of tinnitus (P<0.05). Conclusion Higher intensity, longer exposure to noise, and more cumulative noise exposure associate with a higher risk of tinnitus. Wearing hearing protective device can reduce the risk of tinnitus. Tinnitus in noise-exposed workers can precede the presentation of abnormal hearing loss.

ABSTRACT

Objective:To explore the mechanism of phase-transition fluorocarbon nanomaterials and evaluate its synergistic efficacy on microwave ablation (MWA).Methods:A novel phase transition nanodroplet (PTN) was designed with poly (lactic-co-glycolic acid) (PLGA) as the shell and perfluorocarbon (PFC) mixture as the core. Based on that, a phase-transition mechanism of microwave droplet vaporization (MWDV) was explored, which was based on the thermal phased transition. The basic physicochemical properties and biological characteristics of PTN were monitored by scanning electron microscope (SEM), dynamic laser light scattering (DLS), in vitro hemolysis and CCK-8 experiment.Based on the gel-hole model experiment in vitro, the phase transition of PTN were monitored; based on the live/dead cell double staining kit, flow cytometry and cytotoxicity test, the synergistic efficacy of phase-transition PTN on microwave ablation, which was mediated by MWDV was evaluated. Results:The phase-transition temperature of PTN was exactly the boundary temperature of microwave ablation (60 ℃) when the ratio between perfluoropentane (PFP) and perfluorohexane (PFH) in the core of PTN was 3∶2. Furthermore, the smart proportional PTN didn′t only have good stability and biocompatibility, but also could enhance the two-dimensional ultrasonic imaging and increase the efficacy of MWA under the mediation of MWDV.Conclusions:MWDV can be treated as a phase-transition mechanism of fluorocarbon nanomaterials, which provides a potential synergistic strategy for the thermal ablation of tumors.

ABSTRACT

Abdominoscrotal hydrocele is rare in clinic. In the past, routine examination and diagnosis were difficult, easy to be misdiagnosed. The daily operations were mostly completed through the groin area or abdominal incision, the wound is large. The application of laparoscopy can clearly diagnose the abdominoscrotal hydrocele through "springing back ball" sign, and can cure the disease by laparoscopic resection of interperitoneal mass and closure of the internal ring. It is worthy of clinical application. In this article, we summarized and analyzed the clinical experience of 15 cases of children with abdominoscrotal hydrocele diagnosed and treated by laparoscopy, to explore the value of the laparoscopic technology in the diagnosis and treatment of the abdominoscrotal hydrocele.

ABSTRACT

Objective:To assess the efficacy and safety of 100 units of botulinum toxin A (BTX-A) intradetrusor injection in patients with overactive bladder.Methods:From April 2016 to December 2018, 17 tertiary hospitals were selected to participate in this prospective, multicenter, randomized, double-blind, placebo-controlled study. Two phases of study were conducted: the primary phase and the extended phase. This study enrolled patients aged 18 to 75 years who had been inadequately managed by anticholinergic therapy (insufficient efficacy or intolerable side effects) and had spontaneous voiding with overactive bladder. Exclusion criteria included patients with severe cardiac, renal and hepatic disorders, patients with previous botulinum toxin treatment for 6 months or allergic to BTX-A, patients with urinary tract infections, patients with urinary stones, urinary tract tumors, diabetes mellitus, and bleeding tendency. Eligible patients were randomly assigned to BTX-A group and placebo control group in a ratio of 2∶1. Two groups of patients received 20 intradetrusor injections of BTX-A 100U or placebo at the depth of the submucosal muscle layer respectively under cystoscope, including 5 injections at the base of the bladder, 3 injections to the bladder triangle, 5 injections each to the left and right walls and 2 injections to the top, sparing the bladder neck. As a placebo control group, patients received same volume of placebo containing no BTX-A and only adjuvant freeze-dried preparations for injection with the same method. A combination of gelatin, sucrose, and dextran served as adjuvants. Average micturition times per 24 hours, urinary incontinence (UI) episodes per day, average micturition volume per day, OAB symptom score(OABSS), and quality of life (QOL) score were recorded at baseline and the 2nd, 6th and 12th week after treatment. The primary efficacy endpoint was the change from baseline in the average micturition times per 24 hours at the 6th week after treatment. The secondary efficacy endpoints included the change from baseline in the average micturition times per 24 hours at 2nd and 12th week, as well as the change from baseline in the OABSS, QOL score, average frequency of urgency and UI episodes per day, urgency score, average micturition volume per day at 2nd, 6th and 12th week after treatment. Patients were followed for 12 weeks to assess adverse events (AEs). After assessed at week 12, if the micturition times has decreased less than 50% compared to baseline and the patient is willing to receive retreatment, then patients could enter the extended trial phase. In that phase, patients in both groups were injected with 100 units BTX-A from 12th week onwards and then followed up the same indicators for 12 weeks.Results:216 patients were enrolled in this trial (144 cases in the BTX-A group and 72 cases in the placebo control group). Baseline characteristics such as age (47.75±14.20 in the BTX-A group and 46.39±15.55 in the control group), sex (25 male/117 female in the BTX-A group and 10/61 in the control group), and disease duration (0.51 years in the BTX-A group and 0.60 years in the control group) were balanced between the two groups( P>0.05). A marked reduction from baseline in average micturition times per 24 hours was observed in all treatment groups at the 6th week and the reduction of the two groups was statistically different ( P<0.001 and P=0.008 respectively). Compared with the baseline, the average micturition times per 24 hours at the 6th week decreased from baseline by 2.40(0.70, 4.60)times for the BTX-A group and 0.70(-1.00, 3.30) times for the placebo control group respectively, and the difference between the two groups was considered to be statistically significant ( P=0.003). The change rates of average micturition times per 24 hours from baseline at the 6th week of the two groups were (16±22)% and (8±25)% respectively, and the difference between the two groups was statistically significant ( P=0.014). Compared with the baseline, the average micturition times per 24 hours at 2nd and 12th week decreased by 2.00(0.00, 4.00)and 3.30(0.60, 5.03)for the BTX-A group, 1.00(-1.00, 3.00)and 1.70(-1.45, 3.85)for the placebo control group respectively. The difference between two groups was considered to be statistically significant ( P=0.038 and P=0.012); the changes of average urgency times per day for the BTX-A group and the control group at the 2nd, 6th and 12th week were 2.00(0.00, 4.30)and 2.40(0.30, 5.00), 3.00(0.30, 5.70)and 0.70(-1.30, 2.70), 0.70(-1.30, 3.00) and 1.35(-1.15, 3.50), respectively. There were significant differences between two groups at the 2nd, 6th and 12th week, ( P=0.010, P=0.003 and P=0.025, respectively). The OABSS of the BTX-A group and the control group at the 6th week decreased by 1.00(0.00, 4.00)and 0.50(-1.00, 2.00) compared with the baseline, and the difference between the two groups was statistically significant ( P=0.003). 47 cases of BTX-A group and 34 cases of placebo control group entered the extended trial phase, and 40 and 28 cases completed the extended trial phase, respectively. The average micturition volume per 24 hours changed by -16.60(-41.60, -0.60)ml and -6.40(-22.40, 13.30)ml, (-35.67±54.41)ml and(-1.76±48.69)ml, (-36.14±41.51)ml and (-9.28±44.59)ml, (-35.85±43.35)ml and(-10.41±40.29)ml for two groups at the 12th, 14th, 18th and 24th week, and the difference between two groups was statistically significant at each follow-up time ( P=0.01, 0.006, 0.012 and 0.016, respectively). There was no significant difference in other parameters( P>0.05). However, adverse reactions after intradetrusor injection included increased residual urine volume (27 in the BTX-A group and 3 in the control group), dysuria (21 in the BTX-A group and 6 in the control group), urinary infection (19 in the BTX-A group and 6 in the control group), bladder neck obstruction (3 in the BTX-A group and 0 in the control group), hematuria (3 in the BTX-A group and 1 in the control group), elevated alanine aminotransferase (3 in the BTX-A group and 0 in the control group), etc. During the follow-up period, there was no significant difference in the other adverse events between two groups except the increase of residual urine volume( P<0.05). In the primary trial phase, among the 27 cases with increased residual urine volume in BTA group, only 1 case (3.70%) with PVR more than 300 ml; the PVR of 3 patients in the placebo group was less than 100 ml. The increase of residual urine volume caused by the injection could be improved or disappeared with the passage of time. Conclusions:Intradetrusor injection of Chinese BTX-A improved the average micturition times per 24 hours, the average daily urgent micturition times, OABSS, and average micturition volume per time, and reduced the adverse effects in patients with overactive bladder.Chinese BTX-A at dose of 100U demonstrated durable efficacy and safety in the management of overactive bladder.

ABSTRACT

It is important to investigate the mechanical effects of morphology of prostatic urethra (PU) for benign prostatic hyperplasia (BPH). PU and bladder neck transverse diameter ratio (RPU-1), which related to vortex, and their influence on urine flow were observed by CFD. The results showed that vortexes appeared and expanded with increasing RPU on both sides of PU when RPU-1>0.79, and velocity of external urethral orifice decreased gradually. CFD is an available method for urodynamics research. The quantitative simulation of the relationship between RPU-1 and vortex was proposed for the first time, providing a new idea for advancing theory of PU lumen repair in BPH.

ABSTRACT

Objective To study urodynamic changes of urine at different degrees of hydronephrosis based on computational fluid dynamics (CFD) method, so as evaluate the influence of hydronephrosis degree on kidneys’ ability to discharge stones. Methods Twelve models, including the branched pelvis Model A (normal hydronephrosis A1, mild hydronephrosis A2, medium hydronephrosis A3, severe hydronephrosis A4 models), mature ampullary pelvis Model B (normal hydronephrosis B1, mild hydronephrosis B2, medium hydronephrosis B3, severe hydronephrosis B4 models), and embryo pot abdominal pelvis Model C (normal hydronephrosis C1, mild hydronephrosis C2, medium hydronephrosis C3, severe hydronephrosis C4 models) were established. The urine flow velocity and velocity vector at the neck of the kidney, the outlet of the renal pelvis were calculated by CFD method. Results As the degree of hydronephrosis increased, the flow velocity of urine at the neck of the kidney and the outlet of the renal pelvis decreased. The urinary shearing force of the stones and the kidney’s ability to discharge stones gradually decreased, whereas the circulatory stagnation zone and the velocity boundary layer in kidney aggregate system gradually increased. Conclusions Hydronephrosis can cause changes in urodynamics of the urine. Therefore, the effect of hydronephrosis with different degrees on the patient’s ability to discharge stones after surgery should be fully considered, so as to choose an appropriate treatment method for kidney stones in clinic.

ABSTRACT

Objective:To investigate the 2 years’ efficacy of intravesical instillation of domestic BCG versus epirubicin in the prevention of recurrence of intermediate-risk or high-risk non-muscular invasive bladder cancer and predictive factors of BCG instillation.Methods:From July 2015 to June 2020, 18-75 years old patients with moderate to high-risk non muscle invasive bladder cancer (NMIBC) confirmed by pathological examination were involved. The ECOG score was 0-2. Exclusion criteria included ①immune deficiency or impairment (such as AIDS), using immunosuppressive drugs or radiotherapy, suspected allergic to BCG or epirubicin or excipients of the two drugs, fever or acute infectious diseases including active tuberculosis or receiving anti tuberculosis treatment, with severe chronic cardiovascular and cerebrovascular diseases or chronic kidney disease; ②combined with other urogenital system tumors or other organ tumors; ③combined with muscle invasive bladder urothelial carcinoma (≥T 2); ④undergoing chemotherapy, radiotherapy or immunotherapy within 4 weeks (immediate instillation after surgery not included); ⑤ pregnant or lactating women; ⑥ comfirmed or suspected bladder perforation; ⑦gross hematuria; ⑧cystitis with severe bladder irritation that may affect the evaluation; ⑨participat in other clinical trials within 3 months; ⑩alcohol or drug addiction; ?any risk factors that may increasing the risk of patients. Epirubicin 50 mg was irrigated immediately after the operation(TURBT or laser resection). The patients were randomly divided into BCG15 group, BCG19 group and epirubicin group by the ratio of 2∶2∶1, and the patients were maintained intravescical instillation for 1 year. The recurrence and adverse events of the three groups were compared. Univariate and multivariate analysis was performed to predict the risk factors of BCG irrigated therapy failure. Result:By June 15, 2020, the median follow-up duration was 22.1 months(12.1, 32.3), and there was no statistical difference between the groups ( P=0.9024). There were 274 patients enrolled in BCG19 group, 277 patients enrolled in BCG15 group and 130 patients enrolled in the epirubicin group. The drop-off rate was 16.6%(113 cases)and made no difference between groups( P=0.6222). There were no significant difference in age, gender, BMI, or ECOG score( P>0.05). During the follow-up, 116 cases was detected recurrence or progression. The recurrence rate of the three groups was 14.2% and 14.8% in BCG19 group and BCG15 group, and 27.7% in the epirubicin group. There was no difference in recurrence rate between BCG19 and BCG15 group( P=0.9464). The recurrence rate of BCG19 group was lower than that of the epirubicin group ( P=0.0017). The recurrence rate of BCG15 group was lower than that of the epirubicin group ( P=0.0020). There was no difference in the cumulative recurrence free survival rate between BCG19 and BCG15 group (95% CI0.57-1.46, P=0.7173). The cumulative recurrence free survival rate of BCG 19 group was better than that of the epirubicin group( HR=0.439, 95% CI0.26-0.74, P=0.0006), and the cumulative recurrence free survival rate of BCG15 group was better than that of the epirubicin group ( HR=0.448, 95% CI0.29-0.80, P=0.0021). The total incidence of adverse events in 19 BCG19, BCG15 and epirubicin group were 74.5%, 72.6% and 69.8% respectively. There was no difference in the incidence of adverse events between BCG19 and BCG15 group( P=0.6153). The incidence of adverse events in epirubicin group was lower than that of BCG19( P=0.0051) and BCG15( P=0.0167) groups.There was no significant difference in the incidence of serious adverse events (SAE) among the three groups ( P=0.5064). Log rank test univariate analysis and Cox risk regression model multivariate analysis showed that the history of bladder cancer recurrence( HR=6.397, 95% CI1.95-20.94, P=0.0001)was independent risk factor for BCG irrigation failure. Conclusions:The 2 years’ efficacy of intravesical instillation of domestic BCG is better than than of epirubicin with good tolerance and safety. There is no difference between BCG19 and BCG15 group. BCG doesn’t increase SAE compared with epirubicin. Recurrence status was an independent prognostic factor regarding recurrence-free survival.

ABSTRACT

Objective:To explore the effect of improved urethral irrigation on urethral stricture in patients with closed bulbar urethral injury.Methods:The clinical data of 65 male patients with closed bulbar urethral injury complicated with difficult catheterization from January 2014 to January 2018 in the First Hospital of Shanxi Medical University were retrospectively analyzed. Among them, 30 cases were treated with flexible cystoscope-guided catheterization and external urethral orifice nursing (routine group), and 35 cases were treated with flexible cystoscope-guided catheterization and urethral drug flushing (improved group). The incidence of urethral stricture 1 and 6 months after catheter removal, number of urethral dilatation and maximum urinary flow rate 6 months after catheter removal, visual analogue score (VAS) during indwelling catheter were compared between 2 groups.Results:Both groups indwelled the catheters successfully. During indwelling catheter, the inflammatory secretion in improved group was less and thinner than that in routine group. There was no significant difference in the incidence of urethral stricture 1 month after catheter removal and VAS during indwelling catheter between 2 groups ( P>0.05); the incidence of urethral stricture and number of urethral dilatation 6 months after catheter removal in improved group were significantly lower than those in routine group: 5.7% (2/35) vs. 26.7% (8/30) and (7.1±1.0) times vs. (11.4±1.8) times, the maximum urinary flow rate 6 months after catheter removal was significantly higher than that in routine group: (19.8 ± 2.9) ml/s vs. (16.3±2.3) ml/s, and there were statistical differences ( P<0.05 or <0.01). Conclusions:The system of improved urethral irrigation can be easily fabricated and can achieve convenient application. This improved treatment can facilitate the discharge of urethral secretions, alleviate the urethral inflammation, reduce the urethral scar formation, and can prevent the incidence of bulbar urethral stricture effectively.

ABSTRACT

Objective To observe the effect of recombinant human erythropoietin injection (RHEI) assisted with mild hypothermia on the clinical efficacy and safety of children with hypoxic-ischemic encephalopathy (HIE). Methods From January 2015 to December 2017, 110 children with HIE were treated in Shijiazhuang No.1 Hospital. Fifty-five children with routine treatment were taken as Western medicine routine treatment group. In addition, 55 children treated with mild hypothermia combined with RHEI were taken as mild hypothermia+RHEI group. Both groups were treated for 14 days and followed up for 10 months. The neonatal behavioral neurological assessment (NBNA) score, mental development index (MDI), psychomotor development index (PDI), myelin basic protein (MBP), S100B protein and neuron specific enolization enzyme (NSE), nerve growth factor (NGF), brain derived neurotrophic factor (BDNF), insulin growth factor-1 (IGF-1), growth hormone (GH), and differences in clinical efficacy in two groups were compared, and the occurrence of adverse reactions was observed. Results The NBNA, MDI, PDI, NGF (μg/L), BDNF (ng/L), IGF-1 (pg/L), and GH (pg/L) of two groups after treatment were higher than those before treatment (the Western medicine routine treatment group: 33.72±3.19 vs. 26.81±2.38, 78.95±5.51 vs. 71.39±4.24, 79.62±4.93 vs. 71.84±4.15, 123.74±22.98 vs. 104.29±15.36, 1 518.35±174.92 vs. 1 197.28±148.43, 38.25±4.96 vs. 23.16±2.87, 39.27±5.24 vs. 20.97±3.15; the mild hypothermia+RHEI group: 39.82±3.36 vs. 26.78±2.53, 84.13±6.29 vs. 71.34±4.27, 85.26±5.74 vs. 71.88±4.13, 145.28±27.52 vs. 104.72±15.41, 1 925.71±204.37 vs. 1 192.61±150.26, 57.94±6.62 vs. 23.13±2.91, 56.43±7.14 vs. 20.94±3.17), NSE (μg/L), MBP (μg/L) and S100B (μg/L) were lower than those before treatment (the Western medicine routine treatment group: 17.05±2.26 vs. 24.96±2.83, 9.71±1.85 vs. 23.14±3.37, 0.93±0.12 vs. 1.49±0.24; the mild hypothermia+RHEI group:12.48±1.94 vs. 25.03±2.81, 5.48±1.42 vs. 23.17±3.35, 0.61±0.07 vs. 1.51±0.25). After treatment, the changes of each index in the mild hypothermia+RHEI group were more significant than those in the control group [NABA:39.82±3.36 vs. 33.72±3.19, MDI: 84.13±6.29 vs. 78.95±5.51, PDI: 85.26±5.74 vs. 79.62±4.93, NSE (μg/L):12.48±1.94 vs. 17.05±2.26, MBP (μg/L): 5.48±1.42 vs. 9.71±1.85, S100B (μg/L): 0.61±0.07 vs. 0.93±0.12, NGF (μg/L): 145.28±27.52 vs. 123.74±22.98, BDNF (ng/L): 1 925.71±204.37 vs. 1 518.35±174.92, IGF-1 (pg/L):57.94±6.62 vs. 38.25±4.96, GH (pg/L): 56.43±7.14 vs. 39.27±5.24, all P < 0.05]. The total effective rate of mild hypothermia+RHEI group was significantly higher than that of Western medicine routine treatment group [94.55% (52/55) vs. 81.82% (45/55), P < 0.05]. There were no serious adverse reactions in the two groups. Conclusion RHEI assisted with mild hypothermia therapy can significantly improve the clinical efficacy and NBNA, MDI, PDI scores of HIE children, reduce the degree of brain injury, and improve the neurological function, with good safety.

ABSTRACT

Objective To observe the effects of 3 neuroprotective measures on the expressions of apoptosis-related factors and their ligands (Fas and FasL) in brain tissue of neonatal rats with hypoxic ischemic brain injury. Methods One hundred and twenty Wistar rats 7 days old were selected as experimental subjects, the rats were divided into four groups: neural stem cell, erythropoietin (EPO), ω-3 unsaturated fatty acid treatment groups and hypoxic ischemic brain damage model group according to random number table method, with 30 rats in each group. Neural stem cell group, EPO group and ω-3 unsaturated fatty acid group were respectively injected with neural stem cells, EPO and ω-3 unsaturated fatty acid, each 5 mL via tail vein after modeling; the hypoxic ischemic brain damage model group was given equal volume of normal saline. At 6, 12, 24, 48 and 72 hours after administration of drug, 6 rats were sacrificed in each group, brain tissue was taken, the mRNA expression levels of Fas/FasL, protein expression levels of Toll-like receptor 4 (TLR4), nuclear transcription factor-κB (NF-κB), tumor necrosis factor-α (TNF-α), interleukin (IL-1β, IL-6) and cell apoptotic rate in hippocampus tissue were measured. Results ① mRNA expressions: the mRNA expressions of Fas and FasL of the 3 experimental groups were significantly lower than those of the hypoxic ischemic brain damage model group, the degrees of descent after administration for 24 hours were the most significant, neural stem cell treatment group < EPO treatment group < ω-3 unsaturated fatty acid treatment group < hypoxic ischemic brain damage model group [Fas mRNA expression (2-ΔΔCt): 140.5±2.9, 156.4±2.5, 165.2±2.7 vs. 173.7±2.8, FasL mRNA expression (2-ΔΔCt): 143.1±4.3, 154.6±1.5, 160.7±1.4 vs. 174.7±2.8], the differences were statistically significant (all P < 0.05). ② Protein expressions: the protein expressions of TLR4, NF-κB, TNF-α, IL-1β, IL-6 of the 3 experimental groups were significantly lower than those of the hypoxic ischemic brain damage model group (TLR4/GAPDH: 0.7±0.2, 0.6±0.1, 0.2±0.1 vs. 1.4±0.1; NF-κB/GAPDH: 6.7±0.4, 5.3±0.1, 1.1±0.2 vs. 11.2±0.3; TNF-α/GAPDH: 14.3±1.4, 11.2±1.2, 3.2±2.1 vs. 23.2±0.5; IL-1β/GAPDH: 9.4±0.2, 7.4±0.3, 2.2±0.3 vs. 13.4±0.1; IL-6/GAPDH: 36.2±4.4, 39.3±1.5, 26.2±2.1 vs. 51.4±1.4, all P < 0.05), the protein expression levels of above indexes in neural stem cell treatment group < those of EPO treatment group < those of ω-3 unsaturated fatty acid treatment group < those of hypoxic ischemic brain damage model group. ③ Apoptotic rates:after drug administration, the apoptotic rates of the ω-3 unsaturated fatty acid group, EPO treatment group, neural stem cell treatment group were obviously lower than the rate of model group [(3.7±0.3)%, (3.4±0.2)%, (2.5±0.1)% vs. (5.5±0.4)%, all P < 0.05]. Conclusion The mRNA expressions of Fas/FasL in the brain of neonatal rats with hypoxic-ischemic brain damage are high, and the treatment with each of the following agents; neural stem cells, EPO and ω-3 unsaturated fatty acid can reduce the mRNA expressions of Fas/FasL in such rats' brain tissues.

ABSTRACT

Objective@#To explore the clinical feasibility and effectiveness of novel preoperative evaluating tool to achieve accurate and quantitative evaluation of renal vascular anatomy for retroperitoneoscopic radical nephrectomy (RLRN).@*Methods@#Two-hundred and fifty one consecutive patients who underwent RLRN for renal tumours from September 2016 to March 2018 were enrolled prospectively, including 154 males (61.4%) and 97 females (38.6%), aged 26 to 84 years with the mean age of 58.7 and mean BMI of 25.8 kg/m2. The tumors were all isolated with the mean size of 5.4 cm. According to presence or absence of vascular correlation events (VCE) and nephrectomy times under endoscope (NTE), all the cases were divided into two groups: the common group (VCE, NTE <60 min) and the difficult group (no VCE, NTE ≥60 min). With the help of preoperative three-dimensional reconstruction, the specific and crucial arteriovenous anatomical features were recorded, which consist of side, count, spatial configuration and density of the vessel to be processed. After univariable analysis, multivariable analysis with logistic regression was performed for the selected risk factors. Individualized reno-vasculature evaluation for nephrectomy were established, when the value of risk factors were assigned separately according to its correlation and clinical practice.@*Results@#There was no statistical significance between common group and difficult group in the aspects of gender, age, BMI, maximum diameter of the tumor, R. E.N.A.L. score and PADUA score. There were statistical significance between common group and difficult group in the aspects of N (number of total vessels), D (vascular anomalies density), C (3D conformation), S (sides) of pending renal vessels (χ2=125.700, 102.014, 97.090, 12.603, P<0.05). The correlation of N, D, C were closely related (standardized regression coefficient were 0.742, 0.664, 0.324, P<0.05), but S was not significant (P>0.05). SIREN was preliminarily established as a preoperative evaluating tool to achieve accurate and quantitative evaluation of renal vascular anatomy. Of the 5 components of SIREN, N, D were scored on 1 to 3 points, C was scored on 0 to 3 points, E was scored on 0 to 1 point, and S was not scored but showed in terms of L or R. All of these constitute the assessment content with a full score of 10 points except S suffixed by L or R instead of scores. There was a statistically significant difference during low (2-3 points), middle (4-6 points), and high (7-10 points) groups (χ2=126.927, P<0.05) according to the comparisons between low and middle, low and high, as well as middle and high (χ2=90.997, 7.195, 91.679, P<0.05).@*Conclusions@#In virtue of the renal vascular scoring system named after SIREN by 3d reconstructing, the spatial structure information of the renal vascular system can be obtained accurately and expressed directly before operation, the difficulty of vascular treatment can be predicted, the preoperative planning can be optimized, and the accurate quantitative evaluation of renal vascular anatomical structure can be achieved to further improve the surgical safety and efficiency.

ABSTRACT

Objective@#To analyze the causes of complication of early acute kidney injury (AKI) in four severely burned patients, and to explore the related treatment methods.@*Methods@#The clinical data of 4 patients with severe burn complicated with early AKI admitted to Guangzhou Red Cross Hospital Affiliated to Medical College of Jinan University (hereinafter referred to as our hospital) from June 2014 to December 2017 were retrospectively analyzed. All the patients were male, aged 23-33 (30±5) years old, with depth of burns ranged from deep partial-thickness to full-thickness, complicated with myofascial compartment syndrome of extremities and varying degrees of striated muscle injury, and treated in other hospitals before transfer to our hospital. The patients were numbered from small to large according to the total burn area. The total burn area of patients No. 1, 2, 3, and 4 was 10%, 80%, 90%, and 95% total body surface area respectively, their occurrence time of early AKI was 48, 11, 29, and 48 hours after injury respectively, and their time of arriving our hospital was 60, 11, 29, and 144 hours after injury respectively. Hypovolemic shock occurred in patients No. 2 and 3 at admission to our hospital. All the patients received continuous renal replacement therapy (CRRT) after admission to our hospital. Under the support of hemodynamic monitoring and organ function monitoring, the limbs complicated with myofascial compartment syndrome were incised, thorough decompression exploration was performed, and necrotic muscle tissue was removed or amputation was performed. After escharectomy and decompression of limbs, fresh granulation wounds were formed by temporarily covering wounds with Jieya dressing skin or pig skin, multiple debridements, and vacuum sealing drainage. Fresh granulation wounds and other wounds underwent staged eschar excision and shaving were covered with autologous Meek skin graft, particulate skin graft, reticular skin graft and small skin graft respectively. The treatment outcome, CRRT time, operation times, time of recovery of serum creatinine and myoglobin, length of hospital stay, and follow-up were recorded.@*Results@#All the 4 patients were cured after transfer to our hospital. Among them, totally 5 limbs of patients No. 1 and No. 4 underwent amputation because of complication of myofascial compartment syndrome and a large amount of necrotic muscle which could not be preserved. Patients No. 1, 2, 3, and 4 were treated with CRRT for 19, 35, 14, and 25 days respectively and performed with operation for 5, 6, 10, 8 times respectively. Serum creatinine of patients No. 1, 2, 3, and 4 returned to normal on 22, 35, 37, and 48 days after transfer respectively, and their serum myoglobin returned to normal on 18, 28, 25, and 30 days after transfer respectively. Patients No. 1, 2, 3, and 4 were hospitalized for 52, 105, 148, and 156 days and discharged after basic wound healing. Follow-up for 1 to 36 months showed no abnormal renal function in 4 patients.@*Conclusions@#The early AKI in patients No. 1 and 4 was caused by rhabdomyolysis after severe burn complicated with myofascial compartment syndrome, while that of the other 2 cases were also related to hypovolemic shock and poor renal perfusion. The success rate of early AKI treatment in severely burned patients can be effectively improved by removing the causes of diseases at the same time of CRRT and actively treating burn wounds under the support of organ function and hemodynamic monitoring.

ABSTRACT

Objective To evaluate the feasibility and safety of simultaneous flexible ureteroscopic in the treatment of bilateral upper urinary tract stones from systemic stress response and immune function changes. Methods Sixty bilateral upper urinary tract stones patients who had underwent flexible ureteroscopic lithotripsy (FURL) from December 2015 to December 2017 were selected. The patients were divided into simultaneous FURL treated bilateral upper urinary tract stones (group A, 29 cases) and FURL treated unilateral upper urinary tract stones (group B, 31 cases) according to the treatment method. The perioperative period indexes were recorded. The serum epinephrine (E), norepinephrine (NE), cortisol and peripheral blood T lymphocyte subsets 1 d before operation and 1, 3, 5 d after operation were detected. Results There were no statistical differences in length of stay in hospital, incidence of postoperative complications and stone clearance rate between 2 group (P>0.05). The operating time in group A was significantly longer than that in group B: (108.3 ± 11.5) min vs. (86.9 ± 13.3) min, and there was statistical difference (P<0.05). There was no statistical differences in serum E, NE, cortisol and peripheral blood CD3+, CD4+, CD8+, CD4+/CD8+ during perioperative period between 2 groups (P>0.05). The E, NE and cortisol levels only 1 d after operation in 2 groups were significantly higher than those before operation, and there were statistical differences (P<0.05); there were no statistical difference between 3 d after operation and before operation (P>0.05). Compared with those before operation, the peripheral blood CD3+, CD4+and CD4+/CD8+levels 1 and 3 d after operation in 2 groups were significantly lower, the CD8+ was significantly higher, and there were statistical differences (P<0.05); compared with those 1 d after operation, the peripheral blood CD3+, CD4+and CD4+/CD8+levels 3 d after operation in 2 groups were significantly higher, the CD8+was significantly lower, and there were statistical differences (P<0.05); There were no statistical differences in peripheral blood CD3+, CD4+, CD8+and CD4+/CD8+ levels in 2 groups between 5 d after operation and before operation (P>0.05). Conclusions It is feasible, safe and effective to perform simultaneously flexible ureteroscopic for bilateral upper urinary tract calculi patients. And this treatment will not increase the risks of transient adrenal dysfunction and immunosuppression.

ABSTRACT

Objective To study the application effect of systematic emergency nursing process in treatment of neonatal hypoxic ischemic encephalopathy (HIE). Methods One hundred and four neonates with HIE who were treated in the First Hospital of Hebei Medical University from January 2016 to January 2018 were selected as the subjects of this study, and they were divided into a control group and a study group according to different nursing care process, with 52 cases in each group. The infants in the control group were resuscitated according to conventional traditional first aid measures, while the infants in the study group received systematic emergency nursing care process on the basis of routine first aid (including the preparation of early rescue drugs and equipment; warmth kept in the whole course, the room temperature controlled in 30 - 32 ℃; rapid assessment of maternal delivery methods and procedures, delivery of the newborn and assessment of babies general conditions; performance of preliminary resuscitation for neonate, tracheal intubation for mechanical ventilation, and external chest compression if necessary; close monitor of the vital signs of newborn; symptomatic treatment; reassessment of the baby's disease condition). The successful rescue rate, total rescue time, hospitalization time, neonatal Apgar score and quality of nursing care before and after resuscitation were compared between the two groups. Results The successful rescue rate of the study group was higher than that of the control group [96.2% (50/52) vs. 82.7% (43/52), P < 0.05], and the total rescue time (minutes: 8.9±2.1 vs. 12.4±3.2) and hospitalization time (days: 8.1±2.2 vs. 11.4±2.9) in study group were shorter than those in control group, all the differences being statistically significant (all P < 0.05). After resuscitation for 5 minutes, the Apgar scores of the newborns in the two groups were higher than those before the resuscitation (study group: 8.3±1.1 vs. 2.2±0.7, control group: 6.7±2.0 vs. 2.1±0.9), and after resuscitation for 5 minutes, the Apgar score of the study group was higher than that of the control group (8.3±1.1 vs. 6.7±2.0), the difference being statistical significant (P < 0.05). The scores of rescue technique (5.0±2.9 vs. 2.7±0.6), humanistic care (5.6±2.1 vs. 2.8±0.9), rescue efficiency (5.3±1.2 vs. 3.0±0.6), and rescue effect (5.7±1.3 vs. 2.9±0.8) in the study group were all higher than those in the control group (all P < 0.05). Conclusion The systematic emergency nursing care process can effectively elevate the successful rescue rate of neonates with HIE, shorten the total rescue time and hospitalization time, enhance the rescue effect, and improve the quality of nursing care, thus it is worthy to be widely applied clinically.
